How are you guys preparing for the laser shoot?
I haven't started studying yet but I'm pretty sure there's math involved. I hope it's not just random guessing because that wouldn't be very fun...
Also, it's been a while since I've done a study event. Any general tips from people who've done Optics before or similar events? I mostly mained ID/builds so I'm very rusty on the whole studying thing, haha!

The math is straightforward: angle of incidence = angle of reflection.

The laser is required to be calibrated by the ES so it follows a path down the marked centerline of the apparatus. So in order to hit the target spot, you need to know angle of incidence = angle of reflection, and you need to do some practical geometry.

You can bring premade templates and guides.

To study I reccomend watching videos on each of the topics. One thing I found that helps is looking around and seeing where and in what light refracts.

My strategy back in the day was to always try keeping the beam parallel or perpendicular to the midline for simplicity by putting movable mirrors at 45 degree angles to the midline.

Depending on the angle of the barrier mirror, you can hit it and keep the beam perpendicular/parallel to the midline by putting a movable mirror either perpendicular or parallel to the barrier mirror. If the angle of the barrier mirror with respect to the midline is too small (~25 degrees or less) or too large (~65 degrees or greater), it can be pretty tricky to pull off, so at that point my partner and I would often just skip the barrier mirror altogether.

I've started on the laser shoot. For now, I am just using 2 mirrors and eyeballing the angles, however, I've seen some people use templates.

Are templates worth making and spending time on?

You get four minutes to set your shoot up. Four minutes isn't very long. Anything that will speed up your mirror placement is helpful. This might be templates, to help you set the mirror angles. It might be pre-planning a scheme, so you don't have to stop and think - you just look at the shoot and see which of your pre-planned methods will fit they barrier layout.

That's exactly what's been going through my mind! I thought that it would be enough time but it's barely any time to do anything perfectly above 3 mirrors.

The rule 4.c says:
The LSS has a horizontal flat surface 56 ± 1.0 cm by 35 ± 1.0 cm enclosed by a 2 ± 0.5 cm thick wall.

Is the 56 cm x 35 cm measured from inside the walls or outside? Meaning, does it include the 2x2cm walls, or will the whole LSS end up 60 cm x 39 cm with the walls?

The wording implies that these are internal measurements. These instructions: https://soinc.org/sites/default/files/S ... 101107.PDF
for how to make a LSS agree that the 56 x 35cm dimensions are internal measurements.
